Convection, which is the transfer of heat by thermal currents in the air (or other medium)
If you mean a radiator in a heating system, or in a car, mainly by convection
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.
The sun transfer heat through radiationAnswer'Heat' is not transferred. Rather, 'heat' describes the process of transferring energy. So, your question should read, 'How does the sun transfer energy to earth?", and the answer is by radiation.
Heat can be removed from engine in three different ways. · Conduction : transfer of heat through solid · Convection : heat transfer by movement of molecules of substance · Radiation : transfer across spaces as rays such as use of fins. But, in internal combustion engine, usually heat is removed by passing coolant through air passages around engine blocks through radiator which absorb the heat by air passing over the fins and through radiator core. Air flow is assisted by Fans
Heat can be transferred in 3 ways: Conduction, or through direct contact, Convection, or transfer of heat through a fluid, or Radiation, or heat transfer through space in the form of electromagnetic waves.
ConvectionI'll tell you all i know ;) convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. It's difficult to see in gases, it just kind of, happens. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.Image: http://www.revisionworld.com/files/convection%20copy.jpg
With no water no heat can be transferred through the heater coils.
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
Heat is transferred through contact between molecules.
Heat is transferred through contact between molecules.
It cycles coolant through the engine. Heat from the engine is transferred to the coolant through a heat exchange. The heated coolant then cycles through the system to the radiator, where heat from the coolant undergoes another heat exchange, transferring heat from the coolant to the air which passes through the radiator. Heat will also transfer from the motor to the air forced over the motor by the engine fan.

Heat is transferred through contact between molecules.
Heat transferred in convection occurs through movements of fluids.
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.
Heat is transferred through particles by radiation through space or conduction by touch or convection when the heat flows in a circular pattern
Heat is transferred through the blood
Conductive heat.
